Forget sit-ups — this abs shredder workout sculpts your core in 5 exercises with just 1 dumbbell

 You don't have to spend hours in the gym to tone your abs, and we've mentioned this before. Personal trainer Matt Fox has put together a quick abs workout that only requires one dumbbell. If you're still working out from home, we've got you covered with the best adjustable dumbbells. Additionally, we've hand-picked the best kettlebells on the market if you don't have a dumbbell. However, if you're new to working out or returning from an injury or pregnancy, it's important to consult a medical professional before adding new exercises to your routine. It's also a good idea to have a personal trainer check your form before adding weights to your workout to avoid injury.
